The X-ray Diffraction facility provides the screening, testing and complete data collection from X-ray diffraction of single crystals, either from protein or small molecule compounds. Data is obtained in the in-house X-ray diffractometer or through access to synchrotron macromolecular crystallography beamlines (ESRF, DIAMOND, SLS, SOLEIL, DESY, ALBA). Diffraction is performed using an X-ray diffractometer (with KAPPA four-circle goniometer), and complete data are collected according to experimental requirements. Dedicated software permits indexing, integration, scaling of data and 3D structure solution. Small-Angle X-ray Scattering (SAXS) experiments can be performed through access to synchrotron facilities. A service for Single Crystal X-ray Structure Determination of small molecules is available ( The facility integrates the Portuguese Center for Integrated Structural Biology (PCISBIO), an Affiliate Center of Instruct.
